Hi Ilovetoffeenutfrappe,
There are 3 ways to correct minor misalignment without resorting to traditional metal braces.
1) Invisalign
This provides the most control over even minor tooth movements and is especially popular among adults with relapse from previous orthodontic treatment. Invisalign is the most premium option because of the level of control and customization possible.
Since you have already had one round of comprehensive orthodontic treatment, I would also suggest you consider fixed retainers in addition to removable retainers. Our jawbones are constantly being remodeled throughout life and the teeth shift to accomodat for this.
Fixed retainers can minimize the chances of your teeth shifting again if you stop wearing your removable retainer or if the retainer becomes loose.
2) Retainers with a reset built in
If it turns out that all of your other teeth have maintained their position as they were after your braces were removed and it is only a few (1-4) teeth that are slightly out of alignment, then you may consider a new set of retainers made with a reset done on the misaligned teeth.
This retainer will not fit passively over the misaligned teeth, but will exert some pressure to squeeze the teeth back into position.
To create space for the teeth to move back into line, you may need some interdental sandpapering of the front teeth (IPR). This is similar to what happens with Invisalign but this is suitable only for patients with near-perfect alignment, since we have much less control of how the teeth will move with this option.
This is the cheapest option but with the least predictability.
3) Veneers/crowns
For patients not keen to undergo another cycle of orthodontic treatment, or if they have other issues with the appearance of their teeth (shape, size or severe colour discrepancies), a restorative option may be more suitable.
Veneers or crowns can improve minor tooth alignment issues in a shorter period of time. However, these are irreversible procedures and I would still advise long term use of retainers. Having a full set of veneers or crowns done is the most costly option of the 3 I have presented. Also these artificial materials do have a lifespan and may need replacement down the line.
I hope this is useful. Do try to find a dentist who is comfortable using all 3 different treatment modalities so that you can have an open discussion about which is going to be best for you.
